Evaluation of Human Health Associated With Environmental Risk
The aim of this paper is to understand the adverse health effects associated with food, water and air. Environmental risk can produced adverse health effects among large number of people. Humankind has always faced certain dangers. Risk is an incapable fact of life. However enlightened societies have traditionally sought to minimize avoidable risks. The foods and water are so complex and variable in composition, health risks associated with them can be understood only through the continued pursuit of long term epidemiological investigations. There seems little doubt that about the composition of the human diet strongly influences health status, in both positive and negative ways. The concentrations of chemicals in water supplies depend greatly on source of water and its treatment history. As global trade in basic food commodities continue to increase, so will adverse health impacts spread. Contamination by human pathogens is a significant problem even in developed countries. On a global scale the most significant acute health problem associated with food. Surface water from unprotected watersheds generally has low concentrations of both dissolved minerals and environmental chemicals. Well waters have low concentrations of bacteria and environmental chemicals but often have high mineral concentrations. Poor waste disposal practice may contribute to ground water contamination. Treated surface waters from lakes and rivers in densely populated or industrial areas usually contain a wide variety of dissolved organics and traced metals, the concentrations of which vary greatly with season. Exposure of airborne chemicals vary widely among inhalation environment, The categories include workplace, residence, outdoor ambient air, transportation and public spaces. An exposures airborne chemical varies in terms of composition and concentration. Effective monitoring and exposure control strategies should be in place to achieve exposure results that do not result in adverse changes in health parameters and risk assessment; it can also be used to measure and compare the benefits of possible options concerning the problem of understanding healthenvironmental risks.
